Given any polygon drawn on a piece of paper, possibly with holes, can the paper be folded in such a way that cutting it once in a straight line and then unfolding it produces the desired shape? This is the fold and cut problem, which was solved around 20 years ago by Erik Demaine, Martin Demaine, and Anna Lubiw. We will interactively explore two solutions to this problem. Join me for a fun afternoon of chopping up paper! (Paper and scissors will be provided.)
